High Temperature Resistance alnico magnets
General Description:
1, Alnico magnet material is made by alloying aluminum, nickel and cobalt with iron.
2, Some grades also contain copper and/or titanium. The alloying process is casting or sintering.
3, These constituents, the process and the heat treatment needed to optimize magnetic properties produces hard (Rc45) and brittle parts that are best shaped or finished by abrasive grinding.
4, Sintered Alnico magnet, which are also alumium-nickel-cobalt iron alloys, is usually restricted to smaller sizes. it has slightly lower magnetic properties, but better mechanical strength than cast alnico magnet.
5, Sintered Alnico magnet is widely used in all kinds of sensors, meters, controller speedometer and other applications.
6, Sintered alnico magnets have slightly lower magnetic properties, however they have excellent mechanical properties.
7, Alnico magnets are excellent choices for applications involving vibration and shock as they have good resistance to demagnetization.
Typical applications for Alnico magnet
1.Widely used in applications such as instruments and meters which require very stable temperature properties .
2.Electronic ignition systems ,Watt bour meters ,Volt - amp meters ,medical instruments ,industrial motors ,magnetic reed swiches,generators,hand tools ,vending machines .
